Blade Elevation and Tilting
Mechanism
After five hours of operation, the blade elevation/tilting mechanism
should be checked for looseness, binding, or other abnormalities.
Disconnect the saw from the power source, turn the saw upside
down and pull up and down on the motor unit. Observe any
movement in the motor mounting mechanism. Looseness or play in
the blade raising screw
1
should be adjusted as follows (Fig. 52):
1.
Loosen nut
2
.
2.
Adjust the nut
3
until it is finger-tight against the bracket
4
,
then back off the nut
3
1/6 turn.
3.
Tighten nut
2
. The maximum allowable play of the screw rod
1
is 5/32" (4 m). Place a small amount of dry lubricant (such as
graphite or silicon) on the screw rod
1
at the thrust washer
5
.
Do not oil the threads of screw rod
1
. The screw rod
1
must be
kept clean and free of sawdust, gum, pitch, and other
contaminant's for smooth operation.
NOTE:
If excessive looseness is observed in any other part of the
blade elevation mechanism or tilting mechanism, take the complete
unit to an authorized service center.
Lubrication
All motor bearings are permanently lubricated at the factory and
require no additional lubrication. Lubricate all mechanical parts
where a pivot or threaded rod is present, with graphite or silicone.
These dry lubricants will not hold sawdust.
Care of Blades
Blades become dull even from cutting regular lumber. If you find
yourself forcing the saw forward to cut instead of just guiding it
through the cut, chances are the blade is dull or coated with wood
pitch.
